Every child has a “vision reserve value”, which will lead to myopia!

Abstract: at birth, because the eye development is not perfect, the eyeball is small and the eye axis is short, there will be about 300 degrees of hyperopia at the beginning, and this degree of hyperopia is the so-called “physiological hyperopia reserve value”.

newborns are hyperopia, which is their own talent at birth – vision reserve value, also known as “hyperopia reserve value”. It is similar to “myopia antibody”. If the threshold is too low or used too fast, it will affect the development of children’s vision.

therefore, regular monitoring of hyperopia reserve value is also one of the effective means in the prevention of myopia in adolescents. This incidence rate is incidence of less than 15% of the incidence of juvenile myopia in Germany, and even 1/3 of the incidence rate of myopia in China is not yet available. A very important reason why they can maintain a good vision situation is that they have established a monitoring and early warning system based on “children’s hyperopia reserve value”. What is the relationship between hyperopia reserve and myopia?

before introducing the relationship between the two, we must clarify the three stages of children’s visual development: physiological hyperopia, emmetropia and myopia. When babies with


are just born, they will have hyperopia of about 300 degrees at the beginning because of their imperfect eye development, small eyeball and short eye axis, and this hyperopia degree is the so-called “physiological hyperopia reserve value”.

after physical development, their eyes will tend to mature and their eyesight will reach the normal standard (i.e. emmetropia). This process usually lasts until about 12 years old. If they weaken or disappear too quickly, they will cause myopia.
